Various biological correlates of general intelligence (g) have been reported. Despite this, however, the relationship between neurological measurements and g is not fully clear. We use structural equation modeling to model the relationship between behavioral Wechsler Adult Intelligence Scale (WAIS) estimates of g and neurological measurements (voxel-based morphometry and diffusion tensor imagin...

This study examined gender, socio-economic (SES), and ethnic group differences in academic performance (measured at 14 and 16 years) in a sample of 517 British pupils (mean age=16.5 years). White pupils outperformed their Black and Pakistani counterparts and high SES pupils consistently outperformed their low SES counterparts. Results from two Multiple Indicators Multiple Causes (MIMIC) models ...

In educational settings, researchers are likely to encounter multilevel data with cross-classified structure. However, due to the lack of familiarity and limitations of statistical software for cross-classified modeling, most researchers adopt less optimal approaches to analyze cross-classified multilevel data in testing measurement invariance. We conducted two Monte Carlo studies to investigat...

The availability of data for the size of the “underground economy” (UE) is important for macroeconomic policy. We use fuzzy set theory and fuzzy logic to construct an annual time-series for the (unobservable) New Zealand UE over the period 1968–1994. Two input variables are used—the effective tax rate and an index of the degree of regulation (REG). The resulting UE time-series is compared with ...

In this paper, a Wide Learning architecture is proposed that attempts to automate the feature engineering portion of the machine learning (ML) pipeline. Feature engineering is widely considered as the most time consuming and expert knowledge demanding portion of any ML task. The proposed feature recommendation approach is tested on 3 healthcare datasets: a) PhysioNet Challenge 2016 dataset of p...

tory embarrassment or collapse, which in clinical terms is represented most obviously by a reduction in the blood-pressure. There are a number of causes of that state, that is, it is not a definite clinical entity, it is only a train of symptoms, and it is essential for a reception officer to sort out the cases rather than merely to regard transfusion as efficacious for the treatment of every o...
